In a previous post on some of theweirdest things ever sold, I learned about sales of road kill, excrement art, human kidneys and plots of land on the moon. Readers added to the list, suggesting used panties and breast milk. What could be left?

Well, it seems I missed a few more weird items people have actually sold, like tumbleweeds, paper rocks, flavored bullets and more. Here are eight more weird things for sale.

1. Neuticles

What can you do for a pet who is suffering low self-esteem after being neutered? Buy him a set ofNeuticles, of course. Their creator describes Neuticles as “the revolutionary testicular implant procedure for pets.” The company claims the fake testicles reduce trauma suffered by pets and their owners from regular neutering procedures.

They’re sold primarily through veterinarians (no do-it-yourself kits yet), although pet owners can also buy them directly and then find a vet who will do the implantation. Customers can choose from four models depending on how firm they want their pet’s testicles to be (I’m not kidding — I couldn’t make this stuff up!). Pet owners can also purchase a bumper sticker that says, “My Dog Loves Neuticles.”

Is this just a crazy idea? Maybe not — the company says it’s sold more than 500,000 pairs.

2. Happy Balls

No relation to the previous item on the list. Happy Balls are small smiley-face foam balls meant to go on your car antenna. HappyBalls.com calls itself “The Antenna Ball Superstore,” andINC Magazine says their foam balls are a million-dollar business. The company claims, “We’ve made over 40 million antenna balls in less than 10 years.”

3. Bacon Candles

The Penny Hoarder has written before about Man Cans, candles with “manly” scents, but it looks like the niche is expanding.

Hotwicks Candles has all of the alternative scents you didn’t know you wanted in a candle. Yes, bacon is one of them. Here are three more scents to choose from:

Beer

Sawdust

Urinal cake (seriously)

4. Fake Wishbones

The technical name for a bird’s wishbone is the furcula,according to MentalFloss.com. The tradition of two people breaking it to see who gets the bigger half — and their wish — goes way back to the ancient Etruscans in Italy. But what if you want to make a wish but you don’t have a full chicken or turkey? Get a fake wishbone!

That’s right.LuckyBreakWishbone.com has announced a “Revolutionary Advance in Plastic Wishbone Technology.” A pack of four wishbones made of plastic will set you back just about $4, which is only $1 per wish if you get all the lucky breaks.

5. Animal Mannequins

This product isn’t as strange as it seems. Dog mannequins aren’t meant for displaying the latest canine fashions in the doggie department of some clothing store (although that’s not a bad idea). The realistic animal mannequins made byRescue Critters of Van Nuys, California, are meant for veterinary training.

It makes great sense: We’d all prefer that veterinarians develop and test their skills on fake cats and dogs before going to work on our beloved pets! Kudos to Rescue Critters, which has been building these valuable training tools for 16 years.

6. Pet Rocks

In 1975 it cost just $3.95. Now you’ll have to pay $19.95, but the “travel crate” has been upgraded, and you get a “numbered certificate of authenticity.” In any case, the ongoing costs of caring for a rock makes it cheap compared to any other pet, right? And this time, a couple dollars from each sale goes to help dogs and cats in animal shelters.

7. Flavored Bullets

If you’re going to hunt for your meat, why not flavor it at the same time? That’s the basic idea behindSeason Shot. The idea is to have flavored shots in place of steel pellets in shotgun shells.

The website promises it has five flavors “coming soon,” but the copyright date at the bottom of the page is 2006. Perhaps potential investors shot down the idea.

8. Paper Rocks

For $10 (plus $2 shipping) theOrigami Boulder Company of Dallas will send you a wadded-up piece of paper. The “Wadded Paper Origami Boulder with Haiku,” with its addition of poetry, costs $15 plus shipping. Is this is a joke? The website’s FAQ section offers this answer:

You want joke? Look in mirror, you ugly person! This site real. You order wadded paper origami boulder and see for yourself.

And as for how to read the haiku on the wadded-paper boulder, the site says;

You can’t, but it there… You unfold wadded paper, you ruin artwork! Don’t be stupid. Haiku is there. I even write it in English. You not read it though.

Yes, in case you’re wondering; the order form actually works, so you can apparently get your very own origami boulder if you wish.
